Immunohistochemical marker for Na+ CP type Vα (C-20) and heterozygous nonsense SCN5A mutation W822X in a sudden cardiac death induced by mild anaphyl…

2009

A sudden death likely due to mild anaphylactic reaction in a young man is described. Autoptic, histologic, immunohistochemical, and laboratory findings were strongly consistent with the diagnosis of a mild anaphylactic reaction. Genetic molecular analysis, performed on formalin-fixed, paraffin-embedded tissues, showed a mutation described as W822X in a family with electrocardiographic pattern typical of Brugada Syndrome. It results in a nonsense mutation generating a truncated form of the channel protein. The mutation is due to a point substitution of a guanine with an adenine residue (G2466A). Immunohistochemistry and laser scanning confocal microscopy on sections from heart formalin-fixed…

Children monosensitized to pine nuts have similar patterns of sensitization

2012

Background Several cases of pine nut allergies and anaphylaxis have been reported in the literature, but only few pine nut allergens have been characterized. The aim of this research is to identify through immunoelectrophoretic techniques the major pine nut allergens in a group of children monosensitized to pine nuts. Methods We studied five children with pine nut allergies and no other sensitization to food except to pine nuts, confirmed by in vivo (prick test, prick-to-prick) and in vitro tests (specific IgE determinations [CAP-FEIA]). The protein profile of pine nuts was analyzed by Sodium Dodecyl sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). Immunoblotting was performed after i…
